Securing Internet of Drones With Identity-Based Proxy Signcryption

Internet of Drones (IoD) is a decentralized networking architecture that makes use of the internet for uniting drones to enter controlled airspace in a coordinated manner. On the one hand, this new clan of interconnected drones has ushered in a new era of real-world applications; Small drones, on the other hand, are generally not designed with security in mind, making them exposed to fundamental security and privacy concerns. Limited computing capabilities, along with communication over an open wireless channel, exacerbate these challenges, making the IoD unfeasible for secure operations. In this article, we propose an identity-based proxy signcryption scheme to address these issues. During data transfer between drones and to the cloud server, the proposed scheme supports outsourcing decryption and member revocation. The proposed scheme is based on the notion of Hyper Elliptic Curve Cryptography (HECC), which improves network computation efficiency. We use formal security analysis with the Random Oracle Model (ROM) to evaluate security toughness. The performance analysis of the proposed scheme has also been reviewed in terms of computation and communication costs with the relevant existing schemes. The results obtained from both the security and performance analyses affirm the superiority of the proposed scheme.
